[PyOV] Use nightly OV wheels for auto stubs generation (#31380)
### Details:
- The end goal is to use `openvino_provider` util, but it can't be
tested on forks, so I need to make debug master PRs
- Nightly OV wheels can be tested of forks and are working correctly on
mine
- The motivation of this PR is to have a working stubs automation while
I attempt to test the `openvino_provider` using
https://github.com/nektos/act
- Eventually, once it's tested, the workflow will be improved to use
`openvino_provider`
